Three-Pack Infrared Break Beam Sensor Kit for DIY Projects
✔️ 3-pack IR break beam sensors with transmitter & receiver, 5V

These compact infrared break beam sensor switches come as a 3-piece kit with transmitter and receiver pairs. They detect obstacles by interrupting an invisible infrared beam, making them handy for DIY robotics, automation projects, cabinet sensors, and entry security setups.

✅ 3-piece set includes transmitter and receiver pair in a durable plastic housing for secure breadboard connections
✅ Detects presence up to 30 cm (300 mm, ~12 in) when the beam is interrupted
✅ Operates on 5V DC with built-in regulation and LEDs for power and detection status
✅ Compact form factor fits tight spaces in robots, small appliances, or projects
✅ Compatible with wireless modules for remote control and automation tasks

💡 What is an infrared break beam sensor typically used for in DIY automation projects?

These handy optical switches are used to detect presence or motion without physical contact, triggering control logic in a range of hobbyist and light industrial setups.

• Detect object presence and signal microcontrollers at 5V
• Ideal for obstacle sensing in small robots, door sensors, and simple automation
• Easy to wire to breadboards or compact PCBs
• Works with wireless modules for remote on/off control
